We consider double-parton scattering (DPS) mechanisms of double $c \\bar c$ production and subsequent $cc \\to D^{0}D^{0}$ hadronization as well as double $g$ and mixed $g c\\bar c $ production with $gg \\to D^{0}D^{0}$ and $gc \\to D^{0}D^{0}$ hadronization calculated with the help of the scale-dependent hadronization functions of Kniehl et al. Single-parton scattering (SPS) mechanism of digluon production is also taken into account.
